先前的研究表明,在由食物刺激引起的唤醒状态期间,厌食症患者的心率和血压增加。此外,在咬合过程中,血流交替地流向头部(在颊部肿块的前伸过程中)和消化系统(在回缩过程中)。在这项研究中,切断胸腹连接消除了食物唤醒期间75%的心率反应,切断胸腹连接消除了20-50%的升压反应。记录在腹部神经节从RBHE心脏兴奋和三个LBVC血管收缩运动神经元在减少的准备表明,在这些神经元的活动增加了50和100%,分别在食物唤醒。活动的LBVC细胞是最大的在延长阶段的咬。当LBVC血管收缩运动神经元以食物唤醒期间记录的速率被激发时,可以完全阻塞腹主动脉。我们的结论是,RBHE和LBVC神经元部分介导食物觉醒期间记录的心率和加压反应,并且LBVC的周期性活动对有节奏的咬合行为期间头部和肠道之间血流的周期性交替有显着贡献。
Previous studies have demonstrated that heart rate and blood pressure increase in Aplysia during an arousal state elicited by food stimuli. In addition, during biting, blood flow is routed alternately to the head (during protraction of the buccal mass) and to the digestive system (during retraction). In this study, cutting the pleuroabdominal connectives eliminated 75% of the heart rate response during food arousal, and cutting the pleuroabdominal connectives eliminated 20-50% of the pressor response. Recording in the abdominal ganglion from the RBHE heart excitor and the three LBVC vasoconstrictor motor neurons in a reduced preparation showed that activity in these neurons was increased 50 and 100%, respectively, during food arousal. Activity of the LBVC cells was maximal during the protraction phase of biting. The LBVC vasoconstrictor motor neurons, when fired at the rates recorded during food arousal, can occlude the abdominal aorta completely. We conclude that the RBHE and LBVC neurons mediate, in part, the heart rate and pressor responses recorded during food arousal and that cyclic activity in LBVC contributes significantly to the cyclic alternation of blood flow between the head and the gut during rhythmic biting behavior.
